OPINION OF THE COURT
Appellants, Mary and Michael Joyce, appeal from an order of the United States District Court for the Eastern District of Pennsylvania granting summary judgment to appellee, Super Fresh Food Markets, Inc. (“Super Fresh”). This negligence action originated in the Court of Common Pleas for the County of Philadelphia, Pennsylvania, and was removed on Super Fresh’s motion to federal district court on the basis of diversity of citizenship. The district court held that Mary Joyce was an employee of Super Fresh at the time the relevant events transpired, and, therefore, the Pennsylvania Workmen’s Compensation Act, 77 Pa.Stat.Ann. §§ 1
et seq.
(Pur-don 1952) provided Joyce with her exclusive remedy.
Joyce v. Super Fresh Food Markets, Inc.,
In August 1982, Super Market Services, Inc. (“SMS”) hired Mary Joyce to work in the Super Fresh market located in Levit-town, Pennsylvania. 1 Super Fresh and SMS are both wholly owned subsidiaries of the Great Atlantic & Pacific Tea Company (“A & P”). SMS supplies health and beauty products as well as other merchandise to Super Fresh, A & P, and other stores incorporated under the A & P banner. A & P created SMS for labor and tax reasons. Joyce and other SMS employees are non *945 union; whereas, wage-earners employed by Super Fresh are covered by a collective bargaining agreement with the United Food and Commercial Workers International Union.
Though Joyce was hired by SMS, she worked exclusively in the Super Fresh Lev-ittown store. However, at work she wore an SMS uniform and badge, and her duties were confined to shelving and creating displays for SMS products.
On October 6, 1983, Joyce was performing her duties in the Levittown store. While she was transferring merchandise from shipping boxes to a cart, a large wooden pallet fell and struck Joyce on the leg and foot. As a result, she sustained serious injury, and this lawsuit ensued.
On the day of trial, the district judge held a pre-trial conference during which the attorneys for Super Fresh submitted a motion for summary judgment. Joyce’s attorney objected to any consideration of the motion until he had an opportunity to study it and reply. The trial judge did not rule on the motion at that time and apparently represented to the parties that he would treat the motion and supporting brief as a trial brief. Indeed, there is no entry on the docket sheet indicating that a motion for summary judgment was filed.
The judge also stated at the pre-trial conference that he would trifurcate the trial, and that the first issue to be tried would be whether Joyce was an employee of Super Fresh. Despite the fact that Joyce’s attorney made a jury demand, the judge went on to rule that the first issue would be tried without a jury.
A few days after testimony was taken on the issue of Joyce’s employment status, the trial judge, to the surprise of Joyce’s attorney, entered an opinion and order granting summary judgment to Super Fresh on the ground that the suit was barred by the Pennsylvania Workmen’s Compensation Act. It is from this order that the present appeal was taken. We have jurisdiction under 28 U.S.C. § 1291 (1982).
Appellant attacks the district court’s order on two grounds. First, she claims that summary judgment was entered in violation of Fed.R.Civ.P. 56(c) which requires summary judgment motions to “be served at least 10 days before the time fixed for the hearing.” Second, appellant argues that there remains various genuine issues of material fact, and therefore the case is not ripe for summary judgment. Because we agree with appellant’s second assertion, we need not and will not address the first.
The district court found two bases for concluding that the Workmen’s Compensation Act bars the appellant from recovering in negligence. First, the district court found that Super Fresh was Joyce’s actual employer and therefore was immune from suit under the exclusivity provision of the Act. see 77 Pa.Stat.Ann. § 481 (Purdon 1952) and 77 Pa.Stat.Ann. § 21 (Purdon 1952). Second, the court noted that A & P had incurred all the costs of Joyce’s workmen’s compensation benefits; thus, even if SMS was Joyce’s actual employer, it would be appropriate to “pierce the corporate veil” and grant immunity to all subsidiaries of A & P. We will examine the latter basis first.
The district court cited no authority for its conclusion that sibling corporations should be treated as a single employer for purposes of workmen’s compensation, and Pennsylvania authority indicates that such unitary treatment is disfavored. In
Mohan v. Publicker Industries, Inc.,
Having rejected the district court’s conclusion that Super Fresh and SMS should be viewed as a single entity, we now must decide whether the district court correctly granted summary judgment on the basis of Super Fresh’s assertion that it was Joyce’s actual employer. Joyce claims, of course, that SMS was her employer and that her papers and pleadings raise genuine issues of material fact on the matter, and therefore the district court erred in granting summary judgment. We agree.
In determining which of two affiliated corporations is the employer of a particular employee, a court must ask which corporation has the right to control the work to be done by the employee and the manner of performing it.
Mohan,
We therefore turn to other indicia of the right to control. In determining which of two employers possesses the right to control an employee, Pennsylvania courts have looked at several factors including which party has the right to hire and the right to fire,

Walters v. Kaufmann Department Stores,
The district court found that Super Fresh “clearly” has the right to hire SMS employees such as Joyce. We find the record equivocal on the matter. Both Joyce and her coworker, Betty Dutton, testified that they were hired by Bob Mills, an employee of SMS, after filling out applications that contained the SMS logo. However, Mr. Timothy Courtney, the Vice-President of Taxes of A & P, testified that though prospective SMS employees are initially interviewed by SMS officers, the manager of the Super Fresh store in which the prospective employee is to work has the final word in the hiring decision. Courtney’s testimony was corroborated by John Williams, the manager of the Super Fresh store in which Joyce worked. Williams stated that he personally interviewed Joyce and upon his recommendation Joyce was formally hired by Mills. 4 This testimony, however, is inconsistent with that of Joyce. Both at trial and in deposition, Joyce indicated that she was interviewed only by Mills and other SMS employees. Further, she stated that during this one interview, she was given an on-the-spot offer of employment. Assuming, as we must on review of a grant of summary judgment, that the appellant’s *948 version is correct, we must conclude that no Super Fresh officer was even consulted as to the decision to hire Joyce. The district court’s finding on this matter was, therefore, in error.
The district court also found that Super Fresh “clearly” has the right to remove SMS employees. Again, we find evidence to the contrary in the record, and we must conclude that the district court engaged in fact-finding that is impermissible when ruling on a motion for summary judgment. Williams, the Super Fresh store manager, admitted that the power to fire Joyce rested with Joanne Nice, a SMS supervisor.

At the trial, Williams stated, however, that he had the power to suspend Joyce and other SMS employees, but even this latter testimony is refuted by Williams’ own deposition testimony indicating that if a disciplinary problem arose with an SMS employee, then Nice would be called in to handle it. In sum, there is little evidence supporting the district court’s conclusion that Super Fresh had the power to fire Joyce, and what little evidence exists is certainly controverted in the record. As to the obligation to pay wages, the district court noted “that all employees be they SMS or Super Fresh, received their pay or salary from funds drawn on the A & P payroll system.”
The district court apparently did not consider which party supplied Joyce with the tools of her job. While this indicium of control is often given special prominence in Pennsylvania cases,
see id., Reasner v. Workmen’s Compensation Appeal Board,
Finally, the district court stated, “It is undisputed that SMS employees, such as Joyce, reported on a daily basis to the store manager for direction as to the performance of their duties.”
As the foregoing discussion indicates, the district court made various findings concerning key indicia of control that were either erroneous or controverted in the record. Accordingly, we will reverse the order granting summary judgment and remand the case for trial so that the factual controversies may be resolved by a jury.
Notes
. It is somewhat unclear whether Joyce was hired by SMS or its wholly owned subsidiary, Kwick Save, Inc. For the purposes of this Iitigation, however, it makes no difference whether Kwick Save or SMS was the actual hiring party.
. After citing to Mohan, the district court offered the following functional analysis:
It is undisputed that SMS was created for labor and tax considerations as a support organization for food stores of the parent corporation, A & P, and other subsidiary corporations of the parent. It is also undisputed that the primary duty of a Super Fresh store manager is to insure that his store is operated at a
profit, and that the manager is responsible for all aspects of the store operation. Consequently, he has broad discretion in making decisions which affect the profitability of the store.
Joyce,
. The district court, relying on
Mauk v. Wright,
. This trial testimony is apparently contradicted by Williams’ own deposition testimony in which he indicated that neither Mills nor any other SMS officer participated in hiring Joyce.
. In his trial testimony, Williams claimed that he could dismiss an SMS employee only if he caught the employee stealing.
