Schools and colleges in England will be asked to make sure a minimum number of staff are working on any future strike dates, the government has announced.
Education Secretary Gillian Keegan says she has written to unions to discuss the proposals.
It will be on a voluntary basis at first but, in the future, Ms Keegan said the government could use powers introduced earlier this year.
The Strikes (Minimum Service Levels) Act applies to a wide range of workers.
