Legal aspects
Special attention should be paid to the legal regulations in this context. If a works council exists, consultation with it is essential. This concerns in particular:
If a works council exists: conclusion of a works agreement is necessary (§ 87 BetrVG)
Necessity of major conversion work: Operational change subject to co-determination pursuant to § 111 BetrVG?
Otherwise: Direction right of the employer (e.g. through a corresponding directive)
