Can your boss cut your hours without telling you?

Yes, in most cases, an employer can reduce an employee's hours without prior notice, especially if the employee is at-will, meaning they can be terminated or have their hours changed for any reason that isn't illegal. However, employers are generally expected to communicate such changes to maintain transparency and morale. Specific regulations may vary depending on local labor laws and employment contracts, so it's advisable to review those for any particular provisions.
