Understanding Contract Law and Employment Agreements
It seems to me that many people here on CiteHR need to learn about contract law. A contract is a binding agreement, and breaking that agreement invites all manner of legal complications, which you do not need in your life. It seems that many people skip over this small fact of life.
Reasons for Binding Employment Contracts
For what reason is this company binding people to stay a minimum of 12 months, I wonder? Are they having problems with attrition? Do they want to recoup the cost of recruitment and training new staff? This is a flimsy reason at best, as it is just part of the cost of doing business.
The Importance of Thoroughly Understanding Contracts
It behooves people to stop, think, and thoroughly read and understand before they sign any document. If you are not sure you can commit to the conditions being asked of you, don't sign it. Walk away.
When Employment Conditions Change
Now, in this case, the OP may have signed his life away for 12 months, thinking that it was a good job, it met his requirements, and suited him in all aspects. But the employer shifted the goalposts and changed the conditions of employment. The OP may have a case at law, but only those with deep pockets can afford to stand on principle and fight. And you need lots of evidence to prove your case.
Due Diligence on Prospective Employers
Yet another example where you need to do due diligence on a prospective employer and ascertain to the best of your ability that this is an organization where you want to work and will be treated well.
