Mo. Rev. Stat. § 288.050
1. Notwithstanding the other provisions of this law, a claimant shall be disqualified for waiting week credit or benefits until after the claimant has earned wages for work insured pursuant to the unemployment compensation laws of any state equal to ten times the claimant's weekly benefit amount if the deputy finds:
(1) That the claimant has left work voluntarily without good cause attributable to such work or to the claimant's employer. A temporary employee of a temporary help firm will be deemed to have voluntarily quit employment if the employee does not contact the temporary help firm for reassignment prior to filing for benefits. Failure to contact the temporary help firm will not be deemed a voluntary quit unless the claimant has been advised of the obligation to contact the firm upon completion of assignments and that unemployment benefits may be denied for failure to do so. "Good cause", for the purposes of this subdivision, shall include only that cause which would compel a reasonable employee to cease working or which would require separation from work due to illness or disability. The claimant shall not be disqualified:
(3) That the claimant failed without good cause either to apply for available suitable work when so directed by a deputy of the division or designated staff of an employment office as defined in subsection 1 of section 288.030, or to accept suitable work when offered the claimant, either through the division or directly by an employer by whom the individual was formerly employed, or to return to the individual's customary self-employment, if any, when so directed by the deputy. An offer of work shall be rebuttably presumed if an employer notifies the claimant in writing of such offer by sending an acknowledgment via any form of certified mail issued by the United States Postal Service stating such offer to the claimant at the claimant's last known address. Nothing in this subdivision shall be construed to limit the means by which the deputy may establish that the claimant has or has not been sufficiently notified of available work.
(b) Notwithstanding any other provisions of this law, no work shall be deemed suitable and benefits shall not be denied pursuant to this law to any otherwise eligible individual for refusing to accept new work under any of the following conditions:

(1954) Where substantial evidence supported finding that truck driver was discharged for drinking while on duty in violation of employer's rule and union contract, his disqualification for benefits was proper. Ritch v. Industrial Comm. (A.), 271 S.W.2d 791.
(1958) Offer of employment by former employer must be communicated to claimant so that where former employee who moved to new address and so did not receive letter offering him work would not be disqualified for failing to accept such work.

(1960) Claimant who left her work with appellant solely because of pregnancy, and on being ready to return to work approximately two and one-half months after baby's birth, was told there was no work available, was not entitled to unemployment compensation as she had left work voluntarily without good cause attributable to her or to her employer.

(1960) Where a moving picture projectionist acted as a substitute for the regular projectionist and worked one day a week for several months and finally ceased working because the regular projectionist decided to work full time, the substitute was deemed to have voluntarily left his employment without good cause attributable to his work or employer since the employer had nothing to do with the arrangement between the regular projectionist and the substitute. Kilgore v Industrial Commission (A.), 337 S.W.2d 91.
(1964) Where claimant, who was granted year's leave of absence due to pregnancy and was at first denied permission to return to work but was later allowed to return to work prior to expiration of leave, filed claim for benefits after having made five applications for work with other employers, commission's decision disqualifying claimant was proper.

(1973) Even though claimant received compensation at the approximate rate of $3.54 per hour at the time of her termination, her refusal to accept work at anything less than $3.23 per hour when offered $2.50 per hour justified the determination that she was ineligible for unemployment benefits on the grounds she was unavailable for work. Blackman v. Industrial Commission, Div. of Emp. Sec. (A.), 491 S.W.2d 18.
(1976) Termination of employee for refusal to shave beard held not termination because of misconduct connected with work so as to disqualify employee from waiting week credit or benefits as provided in this section, where evidence was that employee had been assured by his immediate supervisor that employer's rule against beards did not apply to him, that employee had worn beard without question of a rule violation for over a year while receiving satisfactory ratings and a wage increase, and that employee had not acted in wanton or willful disregard of his employer's interest.
