Emma Palmer, from the team, said under the new rules, employees will now have to work for an employer for two continuous years before they can make a claim.
"Previously employees only needed to complete one year's service with a company before they could bring an unfair dismissal claim, but the changes will now come into force for employees taken on after April 6.
"The move is part of the Government's aim to encourage growth by making it less risky for businesses to take new people on, and the longer qualifying period will give employers more time to establish whether someone is right for their business.
"It is hoped that this will also then lead to fewer disputes reaching the employment tribunal stage thanks to the stronger relationship between employers and their staff."
Emma said businesses should take care not to get too carried away though with the new changes and should ensure that the correct procedures were followed from an employee's very first day.
"They will still be able to bring claims which don't have a qualifying period, such as discrimination claims, so it's vital that employers follow the rules very carefully.
"The change is good news for businesses, but the consequences could be an increase in other types of claim which are often more complex and expensive. So companies should take expert advice if they are considering dismissing an employee with less than two years' service to make sure they avoid the pitfalls the system creates."
