In Poland changing location of the job or other important characteristic of the job requires employee's agreement and signing an annex to the contract (yes, every employee must have a contract here). If the employee does not agree, then of course the contract may be terminated but the employer is considered at fault in that case which has some legal implications same as with layoffs, e.g. stating the reason, notifying in advance, paying proper severance package etc.
